Tissue clearing enables researchers to study cancer, neurological diseases and many other disorders that require small-scale, tissue-level imaging, allowing scientists to focus on diseased or damaged structures without losing a global perspective Tissue clearing techniques all aim to make tissues or cell cultures more transparent to overcome their opacity, which prevents them from being penetrated by visible wavelengths of light under the microscope the mechanisms and basic principles of tissue clearing, and summarize the current tissue clearing methods. Moreover, the available imaging techniques and software packages for data processing are also presented. Finally, we introduce the recent advances in applications of tissue clearing in biomedical fields. Tissue clearing con Tissue clearing is about refractive index matching, making sure all components of the cells within a tissue have similar refractive indexes so that light can pass through without scattering. There are 3 methods to achieve tissue clearing: Protein hyper-hydration: TDE, Scale, SeeDB, CUBIC, Fruit, ClearT, FocusClear

Tissue clearing is usually combined with one or more labeling techniques and subsequently imaged, most often by optical sectioning microscopy techniques. Tissue clearing has been applied to many areas in biological research Tissue-clearing methods will be a key technology in the development of drug-carrying nanoparticles, as such methods will allow identification of these agents in the whole rodent and primate bodies.

Discover our tissue clearing reagents to prepare opaque tissues for 3D imaging analysis. Stop spending tedious work on optimizing your method for tissue clearing. With our tissue clearing reagents and protocols to clear different tissues, you will be able to obtain optimal 3D imaging results with ease This electrophoretic tissue-clearing (ETC) enhances the speed of extraction by orders of magnitude such that a large tissue sample e.g. a mouse brain becomes transparent a matter of hours to days instead of days to weeks during passive clearing (Tomer et al., 2014). Lipid clearing using ETC is faster and therefore results in less tissue. As mentioned above, RI matching is the main concept of tissue optical clearing. Tissues are densely packed with many types of substances, including scattering particles with higher RI (1.39-1.52), i.e., fibers, cell membrane, cell nucleus, and cell organelles, and surrounding media with lower RI (1.33-1.37), i.e., interstitial fluid and/or cytoplasm (Figure 2A) Optical-clearing technology allows the reduction of light scattering and absorption in internal biological tissues. This technology allows microscopy techniques, such as confocal laser scanning microscopy, to obtain structural information deep within the internal tissue and also allows for three-dimensional (3D) tissue analysis

Conclusions: CLARITY is an innovative biochemical technology for the structural and molecular analysis of various types of tissue. We developed improved CLARITY methods for clearing of the brain, pancreas, lung, intestine, liver, and kidney, and identified the appropriate experimental conditions for clearing of each specific tissue type Tissue clearing originated in the early 20th century, when Werner Spalteholz experimented with high RI organic solvents (Spalteholz, 1914). Organic solvent-based clearing homogenizes a tissue's RI by the removal of highly scattering lipids and the displacement of water by high RI solvents When using 1×PBS instead of sodium borate, an appropriate antimicrobial agent should be added to the buffer (e.g. a final concentration of 0.01% sodium azide in buffer solutions). Clearing solutions are prepared fresh for each round of tissue clearing, with RT storage (up to several weeks) of excess clearing solution for buffer exchanges

IMAGE: This is a 3D visualization of intact kidney tissue, obtained through the whole-body clearing and staining PARS method : Perfusion-assisted Agent Release in Situ (Yang et al, 2014).view more. The term clearing is related to the appearance of the tissue after it has been treated with a dehydrating agent. Many agents have a similar refractive index to that of the tissue, rendering the tissue clear or translucent. In this step, the dehydrating agent must be removed from the tissue and replaced with a solvent of wax High-throughput sectioning and optical imaging of tissue samples using traditional immunohistochemical techniques can be costly and inaccessible in resource-limited areas. We demonstrate three-dimensional (3D) imaging and phenotyping in optically transparent tissue using lens-free holographic on-chip microscopy as a low-cost, simple, and high-throughput alternative to conventional approaches Immunofluorescence (IF) can provide clear subcellular visualization of proteins, glycans, and small molecules. However, tissue autofluorescence often prevents the effective use of this tool. As will be described, a new technology has recently been developed that significantly lowers autofluorescence and leads to dramatic enhancement in signal.

To allow 3D imaging of an intact cochlea of newborn and juvenile pigs with a volume up to ∼ 250 mm3, we adapted the BoneClear tissue clearing technique, which renders the bone transparent Although we have shown that tissue clearing by PACT (passive CLARITY technique) can alleviate autofluorescence and light scattering problems (Chung et al., 2013; Treweek et al., 2015; Yang et al., 2014) while preserving RNA molecules (Yang et al., 2014), a more robust signal amplification strategy is needed to enable multi-color mapping of. Regarding clearing time, this parameter must be optimized in a case-specific manner. 24 hr clearing may be sufficient for small tissue samples or highly porous tissue, while larger, highly myelinated, or dense tissue sections and whole organs may require > 96 hr. Care must be taken to not overclear the samples and also to check periodically for.

Tissue Clearing Reagents and Kit

The term clearing comes from the fact that the clearing agents often have the same refractive index as proteins. As a result, when the tissue is completely infiltrated with the clearing agent, it becomes translucent (Dapson, 2000) Generally, chemical tissue clearing is performed by a solution consisting of two parts benzyl benzoate and one part benzyl alcohol. However, prolonged exposure to this mixture markedly reduces the fluorescence of GFP expressing specimens, so that one has to compromise between clearing quality and fluorescence preservation. This can be a severe drawback when working with specimens exhibiting.
